After some code reshuffling, the index variables in two functions
are only used in an #ifdef:
fs/ext4/super.c: In function 'ext4_put_super':
fs/ext4/super.c:1262:13: error: unused variable 'i' [-Werror=unused-variable]
fs/ext4/super.c: In function '__ext4_fill_super':
fs/ext4/super.c:5200:22: error: unused variable 'i' [-Werror=unused-variable]
Since all supported compilers now allow having variable declarations
inside of a for() loop, move them into the #ifdef block directly.
Fixes: dcbf87589d90 ("ext4: factor out ext4_flex_groups_free()")

Thanks for the patch. But Nathan has already sent a patch to fix this.
